Optical switches usually use the transmission, control, and sensing of light to achieve the opening or closing of a circuit, and have the advantages of high speed, low loss, and no contact wear. An optoelectronic switch achieves the switching function of a circuit through the control of an optical signal. It usually consists of a light source, a light sensor, and a control circuit, etc. When the light source irradiates the light sensor, the generated optical signal is processed by the control circuit, thereby controlling the on and off of the circuit;

[0003] An optical switch can control the on and off of an optical signal to achieve the switching function of an optical path. By controlling the optical transmission path, it is possible to switch between different optical channels to achieve selective transmission of signals. Since the optical switch is in a working environment, the optical switch will be affected by mechanical stress, causing the connecting wire at the interface of the optical switch to be affected by vibration, impact, or pulling, and the connecting wire at the interface of the optical switch is impacted by mechanical stress, which easily leads to wear of the connecting wire at the interface of the optical switch. Therefore, we propose an optical switch that can reduce wear. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution: an optical switch capable of reducing wear, including an optical switch body 1 and a transmitter 101. A transmitter 101 and a receiver 102 are respectively installed inside the optical switch body 1, and an interface 103 is fixed to the lower side of the optical switch body 1. A wire 104 is connected inside the interface 103. Mounting plates 105 are respectively arranged on both sides of the optical switch body 1. A fixing plate 2 is connected to the outside of the wire 104 at the interface 103, and a block 201 is fixed to the outside of the fixing plate 2. The lower side of the fixing plate 2 is movably connected to a connecting plate 202 through a rotating shaft. A threaded groove 203 is formed on the outside of the connecting plate 202. A limiting tube 204 is sleeved on the outside of the two connecting plates 202. A card slot 205 is formed on the outside of the limiting tube 204. A convex plate 206 is fixed to the inside of the connecting plate 202. A connecting pad 207 is adhered to the surface of the convex plate 206. The block 201 is made of deformable plastic material, and the block 201 is in snap fit with the card slot 205. The threaded groove 203 is in threaded connection with the limiting tube 204. The connecting pad 207 is made of rubber material.

[0025] During specific implementation, according to Figures 1-4The optical switch body 1 can control the on and off of the optical signal to realize the switch function of the optical path. By controlling the transmission path of the light, it can switch between different optical channels to realize the selective transmission of the signal. When the optical switch body 1 is in the working environment, the connecting plate 202 is first rotated to make the connecting plate 202 fit the outer side of the wire 104, and then the card block 201 is pulled outward. The card block 201 adopts a deformable plastic material with a certain deformation ability, so that the card block 201 is disengaged from the card slot 205. At this time, the limit tube 204 can move down along the connecting plate 202, so that the limit tube 204 squeezes the connecting plate 202, and the convex plate 206 drives the connecting plate 206 to move downward. The pad 207 is close to the extruded wire 104. The connection pad 207 is made of rubber material with a certain deformation ability to prevent the convex plate 206 from excessively extruding the wire 104. At this time, the limiting tube 204 is close to the thread groove 203 and rotates. The thread groove 203 is threadedly connected to the limiting tube 204, so that the limiting tube 204 is limited to the outside of the connecting plate 202, so that the connecting plate 202 clamps and limits the wire 104. When the wire 104 is vibrated, impacted or pulled, the connection plate 202 limits the wire 104, which can reduce the mechanical stress between the interface 103 and the wire 104, and prevent the wire 104 of the optical switch interface 103 from being worn.

[0026] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 A toothed plate 3 is slidably inserted inside the optical switch body 1, and the toothed plate 3 is connected to a toothed disc 301. One end of the toothed plate 3 is fixed to the placement plate 105. The toothed disc 301 is movably connected to the optical switch body 1 through a bearing. A sliding groove 302 is provided on the outer side of the toothed plate 3. The sliding groove 302 is slidably connected to a slide plate 303, and the slide plate 303 is fixed to the optical switch body 1. The toothed plate 3 is meshed with the toothed disc 301, and the cross-sectional size of the sliding groove 302 matches the cross-sectional size of the slide plate 303.

[0027] In specific implementation, according to Figure 1 , Figure 2 , Figure 5 and Figure 6 When the optical switch body 1 is installed, the staff can pull the placement plate 105 to make the placement plate 105 drive the tooth plate 3 to move, and the tooth plate 3 is engaged with the tooth disc 301, so that the tooth plate 3 drives the tooth disc 301 to rotate, so that the two tooth plates 3 respectively drive the placement plates 105 to approach or move away from each other, and the cross-sectional size of the slide groove 302 is matched with the cross-sectional size of the slide plate 303, so that the tooth plate 3 is not easily offset when moving, and the distance between the two placement plates 105 can be adjusted, so that the optical switch body 1 can adjust the distance between the placement plates 105 for easy installation.

[0028] In summary, the optical switch body 1 can control the on / off of the optical signal, realizing the switching function of the optical path. By controlling the optical transmission path, it can switch between different optical channels to achieve selective signal transmission. Rotate the connecting plate 202 and then pull the clamping block 201 outwards, so that the limiting tube 204 can move down along the connecting plate 202, making the convex plate 206 drive the connecting pad 207 to approach and press the wire 104. At this time, the limiting tube 204 approaches the thread groove 203 and rotates, causing the connecting plate 202 to clamp and limit the wire 104. When the wire 104 is vibrated, impacted or pulled, the mechanical stress between the interface 103 and the wire 104 can be reduced, preventing the wire 104 of the optical switch interface 103 from being worn. Pull the mounting plate 105, causing the mounting plate 105 to drive the toothed plate 3 to move, so that the distance between the two mounting plates 105 can be adjusted, enabling the optical switch body 1 to adjust the distance between the mounting plates 105 for easy installation.
